Puncture Wound
Definition
A wound where a pointed tooth penetrates tissue to create a hole with a relatively small surface opening and a deeper track. Carnivore canines typically produce puncture wounds. Human incisors produce contusion or abrasion marks rather than deep punctures.
- Cause
- A pointed tooth, typically a carnivore canine
- Wound shape
- Small surface opening with a deeper track
- Human comparison
- Human incisors leave contusion or abrasion, not deep punctures
Common questions
Why does this distinction matter for telling human bites from animal bites?+
Deep, narrow puncture wounds point toward a carnivore's conical canine teeth, while human dentition, with its broader flatter incisors, tends to leave contusions and abrasion arcs, so wound morphology alone helps narrow which species produced a bite.
Can puncture wounds alone identify which species caused the bite?+
Not definitively. Spacing, depth, and arc pattern must still be compared against known dental casts or measurements, since puncture depth and diameter vary with the individual animal's size and bite force.
